In a statement seen by AFP, TSMC confirmed that its 2nm, or N2, technology entered volume production in the fourth quarter of 2025, in line with the company’s earlier timeline. The chips are described as the most advanced in the industry, offering significant gains in transistor density and energy efficiency.

TSMC said the new chips use a leading nanosheet transistor structure, which delivers full-node performance improvements and reduced power consumption. These advances are aimed at meeting the growing demand for energy-efficient computing, particularly as artificial intelligence workloads become more complex and power-intensive.
Production of the 2nm chips is taking place at TSMC’s Fab 20 facility in Hsinchu in northern Taiwan and Fab 22 in the southern port city of Kaohsiung. As the world’s largest contract chipmaker, TSMC supplies semiconductors used across a wide range of industries, from consumer electronics to defence systems, and counts companies such as Apple and Nvidia among its major clients.
The launch comes amid a global surge in AI-related investment. Spending on AI technologies is expected to reach around $1.5 trillion by 2025 and exceed $2 trillion in 2026, according to US research firm Gartner. Advanced chips like TSMC’s 2nm processors are central to powering data centres, servers and next-generation devices.
Taiwan currently produces more than half of the world’s semiconductors and nearly all of the most advanced chips, a position often described as a “silicon shield” that underpins its strategic importance. However, rising geopolitical tensions and concerns over supply chain disruptions have prompted calls for diversified production.
